• The Unity Connection 15 design guide states that Unity Connection supports as many phone systems as needed, up to the maximum number of ports supported per server or active/active pair. disputed in context
• When Unified CM failover occurs while calls are in progress, the voice messaging ports may experience a delay registering with the secondary Unified CM server. in context
• The design guide describes an optional failover configuration with two port groups, each holding half the ports (answering and dial-out), with the Unified CM servers listed in opposite order in each. in context
